hey, got a 1998 vt v6, car wont start up unless I connect my battery to another car or another battery with jumper leads.I have scoured the internet but cant find anything that really covers exactly whats going.... on first thought it was a dead battery so I replaced it, still no luck. car will run fine when its been jumped regardless of how long its driven but when I turn it off it wont start up again - ive literally tried turning it off and straight back on but its like its dead. my dash lights and headlights still work however when I try to crank it over they dim for a couple of seconds. When i try to crank it over without a jump it cranks really slow and stops then starts clicking rapidly. I have checked all fuses, wires, relays, checked for corrosion on terminals and leads ect but nothing is working. I also charged both battery's overnight and it made no difference. checked diagnostics and it came back as system pass. if someone could shed some light and give me their advice it would be greatly appreciated, thanks in advance! Some original photos have not been recovered yet.

have a good look at your earths, make sure they are clean and secure. You could try running a jumper lead from the negative of your battery to the chassis/engine block and then try starting.

ok ill try that now n get back to you Some original photos have not been recovered yet.
